Trim attachment system for appliance

ABSTRACT

A trim system for a door or drawer of an electrical appliance, such as a refrigerator or freezer. The trim system has an engagement structure formed by a retainer having a first engagement surface with a plurality of ratchet teeth. The system also includes a trim member having a first, outward facing, surface and a second, inward facing, surface. The second surface of the trim member includes a protrusion configured to engage with the first engagement surface of the retaining clip, such that the trim member is secured to the engagement structure. The protrusion has a first tooth configured to engage the plurality of ratchet teeth of the first engagement surface. Optionally, the retainer can be formed as a clip, with a second engagement surface opposite the first engagement surface, having a tooth or teeth for engagement with a second tooth of the protrusion.

TECHNICAL FIELD

The present disclosure generally relates to a trim suitable for fitting to electrical (i.e., commercial and/or domestic) appliances (e.g., “home appliances”). Particularly, but not exclusively, it relates to a trim attachment mechanism for the doors or drawers of refrigeration appliances.

BACKGROUND

It is known that commercial and domestic appliances (such as laundry washing and/or drying machines, cookers, refrigeration appliances and dishwashing machines) are often installed into alcoves or spaces defined by a surrounding structure and/or other appliances and cabinetry. These “integrated” (or “built in”) appliances can be installed in several stages, with a main frame or body being installed first followed by the doors and any external, outwardly-facing paneling. This paneling is often attached to a door of the appliance in such a way that its position and/or orientation is adjustable to ensure that the outwardly-facing paneling is correctly positioned and aligned with its surrounding cabinetry panels.

Adjustments of this nature can typically lead to gaps between the paneling and the underlying structure onto which it is mounted. Such gaps are both cosmetically displeasing and furthermore, expose the underlying structure of the door and/or frame, allowing for the ingress of dirt, dust and detritus.

An object of the present invention is to mitigate at least some of the issues mentioned above.

SUMMARY

In accordance with a first aspect of the invention, there is provided a trim system for a door of an electrical appliance, the trim system comprising: an engagement structure comprising a retainer having a first engagement surface, the first engagement surface comprising a plurality of ratchet teeth; and a trim member having a first outward facing surface and a second inward facing surface; wherein the second surface of the trim member comprises a protrusion configured to engage with the first engagement surface of the retainer, such that the trim member is secured to the engagement structure; and wherein the protrusion comprises a first tooth configured to engage the plurality of ratchet teeth of the first engagement surface.

The arrangement of the plurality of ratchet teeth on the first engagement surface and the first tooth of the protrusion enables the protrusion to be selectively advanced within the retainer, i.e. inserted and secured to the retainer to varying degrees, such that the trim member can be repositioned laterally (i.e., in a front-to-back direction) relative to the engagement structure whilst still being held securely.

Optionally, the retainer comprises a retaining clip, the retaining clip formed by the first engagement surface and a second engagement surface opposing the first engagement surface, the second engagement surface having one or more ratchet tooth/teeth, and wherein the protrusion also has a second tooth configured to engage the one or more ratchet tooth/teeth of the second engagement surface.

The addition of a tooth on a second engagement surface helps to prevent the protrusion from being entirely disengaged from the retaining clip, whilst still allowing the protrusion to be advanceable and repositionable along the plurality of ratchet teeth on the first engagement surface.

Optionally, the first engagement surface comprises at least two spaced apart ratchet teeth arranged such that the protrusion may be secured within the retaining clip to at least a first and a second extent.

Optionally, the first engagement surface is provided on a first tab.

Optionally, the second engagement surface is provided on a second tab.

Optionally, the tabs each have a free end and an opposite fixed end attached to a main body of the engagement structure.

Optionally, the fixed end of the tab bearing the first engagement surface is arranged to receive the protrusion of the trim member. This arrangement allows the first engagement surface to deflect when acted on by the protrusion. When the protrusion is partially inserted or withdrawn from the retaining clip, the tab and its ratchet teeth I are able to be deflected away from the protrusion so as to enable the protrusion's first tooth to move back along the plurality of ratchet teeth, towards an opening or entrance of the clip.

Optionally, the free end of the tab bearing the second engagement surface is arranged to receive the protrusion of the trim member. This arrangement allows the second engagement surface to deflect when acted on by the protrusion. The greater flexibility of this arrangement allows the second engagement surface to deflect when acted on by the advancing protrusion such that the protrusion may pass by the tooth/teeth of the second engagement surface and be engaged within the retaining clip.

Optionally, the protrusion is formed of a resiliently flexible material while the clip is formed from relatively inflexible material. This enables the protrusion, rather than the engagement surface(s), to deform and/or deflect as necessary when being inserted into or withdrawn from the retaining clip.

Optionally, faces of the plurality of ratchet teeth of the first engagement surface and/or the tooth or teeth of the second engagement surface, and corresponding faces of the first and/or second tooth of the protrusion, are inclined such that removal of the protrusion from the retaining clip is impeded relative to its insertion. This reduces the chance of the trim member coming loose of its own accord, or otherwise being accidentally disengaged from the retaining clip of the engagement structure.

Optionally, the one or more ratchet teeth of the first and/or second engagement surfaces comprise front and rear faces meeting at an edge, wherein the angles of inclination of the front and rear faces are not the same, with the rear faces being less steep than the forward faces. Accordingly the protrusion may be repositioned in a forward direction along the plurality of teeth of the first engagement surface with relative ease, whereas the withdrawal of the protrusion from the plurality of teeth is more difficult.

Optionally, the trim member and/or engagement structure is substantially elongate, extending predominantly in a longitudinal direction.

Optionally, the plurality of ratchet teeth of the first engagement surface are displaced across a lateral width of the engagement structure, substantially perpendicularly to a longitudinal extension direction of the engagement structure.

Optionally, the engagement structure further comprises one or more abutments configured to prevent relative movement of the trim member in the longitudinal direction of its elongation.

Optionally, the engagement structure is provided on an exposed top or bottom surface of a door or drawer.

Optionally, the trim member has a substantially curved cross-sectional profile.

Optionally, the protrusion comprises a right angle, having a first portion extending in a direction substantially normal to the second surface of the trim member, and a second portion extending in a direction substantially parallel to the second surface of the trim member.

Optionally, the first tooth of the protrusion is located on a first surface of the second portion parallel to the second surface of the trim member.

Optionally, the second tooth of the protrusion is located on a second surface of the second portion opposite the first surface.

Optionally, when the protrusion is located in and engaged by the retaining clip, the first and second engagement surface of the retaining clip are parallel to the second surface of the trim member.

Optionally, the trim member is made of metal and/or the engagement structure is made via injection moulding a plastics material.

In accordance with a second aspect of the invention, there is provided an electrical appliance comprising: a cabinet having an opening closable by a door or drawer fitted thereto, and a trim system for the door or drawer, the trim system comprising: an engagement structure having a retainer having a first engagement surface, the first engagement surface having a plurality of ratchet teeth; and a trim member having a first, outward facing, surface and a second, inward facing, surface; wherein the second surface of the trim member includes a protrusion configured to engage with the first engagement surface of the retainer, such that the trim member is secured to the engagement structure; and wherein the protrusion has a first tooth configured to engage the plurality of ratchet teeth of the first engagement surface.

Other aspects of the invention will be apparent from the appended claim set.

Features from one or more embodiments or configurations may be combined with features of one or more other embodiments or configurations. Additionally, more than one embodiment or configuration may be used together in an electrical appliance, for example a refrigeration appliance, such as a refrigerator or freezer.

DETAILED DESCRIPTION

FIG. 1 shows a trim system 1 configured for use on an electrical appliance, for example a domestic appliance such as a refrigeration appliance 30 (see FIG. 6A or 6B). The trim system comprises an elongate engagement structure 10 and an elongate trim member 20. The engagement structure 10 has a lower surface 12 configured to secure to a top face of a door 40 of the refrigeration appliance 30. The refrigeration appliance door to which the trim system 1 is applied is preferably a “bottom” or lower door or drawer of a multi-compartment cabinet where the top of the door/drawer is, in use, visible to the user. The engagement structure 10 has an upper surface 14 configured to engage with and retain the trim member 20. In an embodiment, the engagement structure 10 is formed via injection moulding a plastics material whilst the trim member 20 is an extruded metal (for example, Aluminium) component, however each component may otherwise be formed of any suitable material depending on their application and desired properties.

FIG. 2 shows the engagement structure 10 in isolation. For securing the engagement structure 10 to the top face of the door 40, the lower surface 12 of the engagement structure 10 is generally shaped to conform to the top face of the door 40 and includes clearances and cut away portions to accommodate the various magnets, brackets and hinge mechanisms 35 found on said top face of the door 40. In an embodiment, the engagement structure 10 further includes through-holes for accepting screws and/or other attachment means for fixing the engagement structure 10 to the door 40. These features enable the engagement structure 10 to be used with multiple door models in different configurations, with the engagement structure being able to accommodate left- and right-handed hinges installed on either end of the door, for example. Upper surface 14 is recessed below front and rear longitudinal walls of the engagement structure 10 such that a longitudinal central channel is formed on or in upper surface 14.

For engaging and retaining the trim member 20, the upper surface 14 of the engagement structure 10 has a series of retainers or retaining clips 16. As shown in FIG. 1 , the upper surface 14 is recessed within the engagement structure 10 and further includes a poke-yoke structure or abutment 18 to ensure that the trim member can only be successfully mounted to the engagement structure in one, correct orientation, while also restricting longitudinal movement of the trim member 20 relative to the engagement structure 10 once mounted and retained. The upper surface 14 of the engagement structure 10 further includes a slot 19 to provide clearance as necessary for surface protrusions found on the door 40 or body of the refrigerator 30.

FIGS. 3A and 3B show various views of the underside of the trim member 20 having legs or protrusions 22 configured to engage the retaining clips 16 of the engagement structure 10. Protrusion 22 may have a first section extending from the underside of trim member 20 and a second section extending from the distal end of the first section and having a barbed tip 23 at its distal end. In the illustrated embodiment, one protrusion 22 runs along a substantial portion of the length of the trim member 20 such that a single protrusion 22 is retaining by multiple retaining clips 16 on the surface of the engagement structure 10. In an alternative embodiment, one protrusion 22 is provided for each retaining clip 16. Accordingly, whilst two protrusions 22 are shown extending along the central, longitudinal axis of the trim member 20, any suitable number or arrangement of protrusions 22 may be employed. As shown in FIG. 3B, the protrusions 22 extend longitudinally along the length of the trim member 20 and are positioned such that they provide clearance for the underlying structures, including the poke-yoke structure 18 of the underlying upper surface 14 of the engagement structure 10 and the hinge mechanism of the door 40. As best shown in FIG. 3A, the protrusions 22 have a right-angle profile (i.e., the first section extends substantially perpendicularly to the underside of the trim member and the second section extends substantially perpendicularly from the distal end of the first section) and the barbed tip 23 has a top tooth 24 and a bottom tooth 25 (see FIG. 4 for teeth 24/25). Ideally, each of top 24 and bottom 25 teeth consist of intersecting front and rear faces meeting at a tip edge/line.

FIG. 4 shows the trim member 20 secured by the engagement member 10, with a protrusion 22 being secured within or beneath a retainer or retaining clip 16. The retaining clip 16 is formed by a first, “U”-shaped member 16A having the distal end of each leg attached to the front longitudinal wall of the engagement structure and extending to or towards the centreline of the central longitudinal channel, and a second, inner tab 16B having an engagement surface on its underside. Inner tab 16B projects from the base of the “U”-shaped member 16A back towards the front longitudinal wall of the engagement member, without contacting the front wall. Both “U”-shaped member 16A and inner tab 16B are substantially co-planar although inner tab 16B is able to flex out of the plane of the “U”-shaped member, particularly upwardly. As shown, the top tooth 24 of the protrusion 22 engages with a set of ratchet or “saw tooth”-shaped teeth 17 dispersed on the engagement surface on the underside of retaining tab 16 in a planar or linear fashion. The retainer or retaining clip 16 may also include a lower engagement surface which is effectively the base or floor of the longitudinal channel formed in the upper surface of the engagement member 10. An opposing lower tooth 17A (preferably a pair of aligned, and laterally-spaced, with respect to upper ratchet teeth 17, lower teeth 17A—see FIG. 5A), facing oppositely to the set of upper ratchet teeth 17, may also form part of clip 16, located on or formed as a part of the floor/base of the longitudinal channel in/on the upper surface 14 of the engagement structure 10 in a manner that enables lower tooth/teeth 17A to flex out of the plane of the floor of the channel, particularly deflecting downwardly. Lower tooth/teeth 17A engage(s) the bottom tooth 25 of the trim member 20 when it is situated on the upper surface 14 with protrusion(s) 22 located in the channel and makes it more difficult to completely remove/disengage the trim member 20 from engagement structure 10. In an embodiment, the contact surfaces of the lower tooth 17A and the bottom tooth 25 are steeper than those of the upper ratchet tooth/teeth 17 and upper tooth 24 such that it requires a greater amount of force to dislodge the trim member 20 from the lower tooth and remove it entirely from the engagement structure 10. It will be appreciated that a retainer having only a first engagement surface with ratchet teeth 17 would be effective at retaining trim member 20.

Whilst the retaining clip 16 and protrusion 22 are depicted in the drawing figures as having seven teeth and two teeth, respectively, any suitable number may be employed.

Though depicted as having a substantially flat cross-sectional profile, the main body of the trim member 20 may have any suitably-shaped profile required by a particular application or selected for its eye-appeal. For example, the trim member 20 may have a substantially curved profile and may be substantially concave of convex.

Similarly, whilst the protrusion 22 and retaining clip 16 are shown as having generally flat profiles, they may be curved or alternatively shaped providing they are able to engage in the manner described above.

In use, the trim member 20 is positioned above the upper surface 14 of the engagement structure 10 and the protrusion 22 is guided into a leading edge or mouth of the or each retaining clip 16 between the “U”-shaped member 16A and the base or floor of the longitudinal channel in/on the upper surface 14 of the engagement structure. The barbed tip 23 of the protrusion 22 is pushed into engagement with teeth 24 and 25 by sliding the trim member 20 towards the front face of the door 40 (i.e., to the right in FIG. 4 ) so that teeth 17 and/or 17A deflect upwardly/downwardly and allow the barbed tip 23 to be positioned as illustrated in FIG. 4 with bottom tooth 25 now retained behind lower tooth/teeth 17A and top tooth 24 now engaged with the set of upper ratchet teeth 17. In an embodiment, the leading faces of the top 24 and bottom 25 teeth of the barbed tip 23 are shaped so as to deflect the “U”-shaped member 16A and its set of upper ratchet teeth 17 and opposing lower tooth/teeth 17A such that the protrusion 22 can advance within the retaining clip 16, with top tooth 24 stepping through engagement with each subsequent ratchet tooth of the set 17. In an embodiment, the top 24 and/or bottom 25 teeth are shaped so as to make retraction/removal of the protrusion 22 from the retaining clip relatively more difficult, for example by arranging the leading (or forward-facing) faces of teeth 24/25 inclined less steeply than the trailing (or rearward-facing) faces. In an embodiment, the set of upper ratchet teeth 17 and/or opposing lower tooth/teeth 17A of the retaining clip 16 are shaped similarly to the shape of teeth 24/25 (i.e., with their leading/forward-facing/insertion faces inclined less steeply than the trailing/rearward-facing/removal faces) so as to allow the protrusion 22 to enter the retaining clip 16 more easily than it can be extracted (i.e., “ratcheting”). By providing a series of teeth in the form of the set of upper ratchet teeth 17, the protrusion 22 may be discreetly advanced within the retaining clip 16, thereby adjusting the front-rear position of the trim member 20 (that is, in the lateral direction of the trim member) relative to the engagement structure 10. Whilst the opposing lower tooth/teeth 17A acts as a back stop to help prevent the protrusion 22 from being entirely withdrawn from the retaining clip 16 and disengaged from the engagement structure 10.

FIG. 5A shows a plan view of a retaining clip 16 on the upper surface 14 of the engagement structure 10 according to an embodiment of the invention. In this embodiment a pair of opposing lower teeth 17A are provided on the engagement structure 10 and are partially surrounded by a cut-away or aperture such that the opposing lower teeth 17A are each provided on the end of a tab or finger extending from the main body of the engagement structure 10. This arrangement provides greater flexibility such that the opposing lower teeth 17A may deflect downwards so as to accept the barbed tip 23 of the protrusion 22 and spring back into place to impede its extraction.

FIG. 5B shows a perspective view up through the body of the engagement structure 10 and depicts the set of upper ratchet teeth 17 provided on tab or finger 16B formed within the “U”-shaped member 16A extending from the sidewall of the engagement structure 10. When engaging the protrusion 22 of the trim member 20, the terminal or free end of the tab is able to deflect owing to its cantilever design and allow the barbed tip 23 to advance along the set of upper ratchet teeth 17. Similarly, when the protrusion 22 is being partially withdrawn, the ratchet teeth 17 located deeper within the retaining clip 16 (i.e., towards the free end of the tab 16B) are able to deflect so that the barbed tip 23 can move to the left in FIG. 4 . This allows the trim member 20 to be retained by the engagement structure during repositioning within the retaining clip 16, thus adjusting the front to rear position of trim member 20 relative to engagement structure 10, and therefore door/drawer 40.

FIGS. 6A and 6B show a refrigerator 30 having lower 40 and upper 40A front doors. Each door has an outer, decorative panel mounted to it, such as outer panel 41. FIG. 6A depicts the refrigerator lower door 40 with the trim system 1 of an embodiment of the present invention removed, whereas FIG. 6B depicts the refrigerator lower door 40 with the trim system 1 installed on the upper surface 14 of its engagement structure 10. The trim system 1 is nevertheless suitable of installation on the top surface of the upper 40A door, or on refrigerators and/or other electrical appliances having only a single door, or on the upper surface of drawers such as freezer drawers, as required. Furthermore, in addition to providing a trim system where the trim member 20 is securely fastened to the door/drawer, the disclosed invention enables a significant range of front to rear adjustment of trim member 20 so that, for example, a gap between the door/drawer and an outer panel of an integrated appliance can be hidden from view while still also covering the underlying structure of the top of the door from view. For this purpose, it will be appreciated from FIG. 4 that the lateral width (from front to rear) of trim member 20 is greater than the front to rear thickness of engagement structure 10 so that, in some embodiments, a total adjustment of around 6 mm in a front to rear direction may be achieved. It will therefore be appreciated that the above-described trim system provides a “no fastener” top trim to the door or drawer of an appliance and so installation and adjustment is relatively simple, convenient, and tool-free.
